    摘要: The present invention relates to a process for preparing carbonates by reacting propylene oxide, ethylene oxide, styrene oxide and/or cyclohexene oxide with carbon dioxide in the presence of one or more catalysts of the formula I where R1 is hydrogen, C1-C6-alkyl, C1-C6-haloalkyl, NR′4—(CH2)2-6—where R′ is C1-C6-alkyl; R2 is hydrogen, C1-C4-alkyl, C1-C4-haloalkyl, halogen, amino, nitro, C1-C6-alkoxy or cyano; R3, R4 are each hydrogen or together are a butadienylene moiety which bears the R5 substituent; R5 is C1-C4-alkyl, C1-C4-haloalkyl, halogen, amino, nitro, C1-C6-alkoxy or cyano; M is Zn(II), Mg(II), Cr(II), Cr(III), Co(II), Co(III), Fe(II) or Fe(III); and X1, X2 are each OCOCH3, OCOCF3, OSO2C7H7 or halogen. More particularly, the invention relates to a process for preparing cyclic carbonates, and to a process for preparing aliphatic polycarbonates using these catalysts I, and to particularly preferred catalysts of the formulae Ia and Ib.
